Data Fields
struct u_pacing_compositor	base

uint64_t	present_to_display_offset_ns
	Very often the present time that we get from the system is only when the display engine starts scanning out from the buffers we provided, and not when the pixels turned into photons that the user sees. More...

uint64_t	frame_period_ns
	Frame period of the device. More...

uint64_t	comp_time_ns
	The amount of time that the compositor needs to render frame. More...

int64_t	next_frame_id
	Used to generate frame IDs. More...

uint64_t	comp_time_max_ns
	The maximum amount we give to the compositor. More...

uint64_t	adjust_missed_ns
	If we missed a frame, back off this much. More...

uint64_t	adjust_non_miss_ns
	Adjustment of time if we didn't miss the frame, also used as range to stay around timing target. More...

uint64_t	margin_ns
	Extra time between end of draw time and when the present happens. More...

struct frame	frames [16]
	Frame store. More...
